To all whom t may concern:

My invention relates to incinerators,"fandV one of the objects of the invention is to provide an incinerator'for the efficient reduction of garbage and other waste.

Another object of the invention is to proi vide improved means for passing the O'aseous products of evaporation and com ustion through flames from the lire chamber.

The invention possesses other features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself tothe showing made by the said drawings and description, as I may adopt variations of the referred form within the scope of my invention as set forth in the claim.

Referring to the drawings:

Figure l is a sectional view taken in the vertical plane passing through the center -of the furnace longitudinally.

Fig. 2 is a sectional view. taken in the vertical plane indicated by the line 2-2 of Fic. 1.

Fig. 3 is a sectional view taken inthe vertical`plane indicated by the line 3-3 of Fig. 1.

Fig. 4 is a sectional view taken in the horizontal plane indicated by the line 4--4 of Fig. 1. I

Fig. 5 is a sectional view taken in the horizontal plane indicated by the line 5-5 of Fig. 1.

The incinerating furnace of my invention is preferably built with brick walls suitably reinforced with iron members 2, and lined with re brick. VA heavy layer 3 of corrugated asbestos, or of magnesia is incorporated lin the walls of the furnace to aid in retaining the heat therein. A receiving or drying chamber 4 is arranged in the front upper portion of the furnace, into which garbage may be introduced through two charging ports 6 and 7 normally closed bg the doors 6 and 7 respectivelylf.` Prefera ly wet garbage is introduced t rough the garbagethroughf'the 'portlin the front wall. The, bottomor fl-fooi oifthedrying chamber:isgformedjby spaced grate;v bars 8 omerlying the fire chamber 9, 'and llying *adjacent the dry garbage charging port 6, and

bythe-relatively thi'liincli-ne'drwall "11 overthe iue 12. The wall 11 forms a drylng platform for the reception of wet gar` bage introduced through the port 7.

The fire chamber' ,9 is provided with a port 13 for the introduction of fuel. Grate bars 14 overlyin the ash pit 16 form the bottom of the re'chamber. vThe Hue 12 underlying the sloping wall 11 connects the lire chamber with the combustion and cinder collecting chamber 17 at the bottom of which an opening normally closed by the door 18 provides a means ,for removing matter accumulated therein. At the bottom, the combustion chamberpis connected by the passage 19 with the base of the stack through which the products of combustion from the furnace pass` into the atmosphere. The dry or relatively dry garbage upon the drying grate 8 is quickly dried out and ignited by the flames from the lire chamber 9. The hot smoke and gases Yfrom this source, and the hot wall 11, heated from the iiue 12, effect the drying of the wet garbage, which gradually works down from the slop-v ing wall 11 onto the dryinof grate 8 where it is ultimately consumed, the' residue falling through the grates and collecting in the ash pit.

Means are provided for passing the gases and vapor arising from the drying material through the ames from the lire chamber. In the vertical sidewalls of the furnace, channels 21 arevdisposed. Preferably the channels extend from the top of the drying chamber 4 downwardly past the drying grate 8 and platform 11 and are continued in the sides of kthe lire chamber 9 and flue 12. When the garbagey is introduced into the drying chamber it eXtends into these channels perhaps for a shortdistance, but the channels are not filled rcompletely and each one still functions as a passage through which the gases and vapor from the drying material are drawn downwardly from .theY

drying chamber into the fire chamber and flue,lwhere mingling with the llames therein, the remaining inflammable matter is reduced and all odors destroyed. The remaining unconsumed gases pass up the stack OFFICE@ ateteaoct. 14,., 1919.

Yport? inthe roofof the-furnace,anddry l into the air. Preferably a recess 23 is out in the sloping Wall l1 opposite each channel so that the opening through the Wall is enlarged.

I claim:

In an incinerator, a drying chamber having a floor formed of a drying grate and a sloping Wall, a charging port in the top Wall of said chamber over said sloping Wall, a second charging port in the end Wall of said chamber adjacent said drying grate, a fire chamber below said drying grate, a combustion chamber, and a flue connecting said fire chamber and said combustion chamber and underlying said sloping floor, the side Wall of said drying chamber being formed With a plurality of channels connecting said drying chamber With said re chamber and fluea said channels extending past the iioor of the drying chamber and being continued in the side Walls of said fire chamber and of said iue.

In testimony whereof I have hereunto set my hand at San Francisco, California, this 4th day of May, 1918.
